Abstract: ABSTRACT     A pig for monitoring the internal surface profile of a pipeline carries a plurality of sensors to trace the surface as the pig traverses the pipeline.  Output signals from the sensors are compared with an expected value and a reference signal generated when they differ by more than a predetermined amount.  The sensor signals are recorded simultaneously with the reference signal.

Abstract: ABSTRACT OF THE DISCLOSURE    Vital transmission checking apparatus is disclosed for a communication channel which transmits quasi-static signals representing several alternative states of a function, e. g., the control function for a signal in a railway control system, one of which states is potentially unsafe.  Each function channel transmits a digital signature code of predetermined length which is continuously repeated in a selected form, e. g., non-inverted, inverted, or alternately inverted and non-inverted, to represent the different states of the func-tion.  To provide a check of proper transmission, the repeated signature code is periodically corrupted in accordance with a predetermined error pattern which is repeated at a lower repi-tion frequency than the code.  The channel receiver is so designed that its output can only be held in the selected state when both the signature code and the error pattern in the received signal are correct.  If a fault is detected, the receiver output is shifted to the most safe state of the func-tion.

Abstract: Abstract The present invention relates to a photopolymerizable composition comprising a polymerizable, polyethylenically unsaturated compound, benzil and/or fluorenone, a specific biphenyl ketone such as para-phenyl benzophenone, and a reducing agent such as a tertiary amine.  The present composition permits rapid and complete curing.  Moreover, in the photopolymerization of compounds sensitive to air inhibition non-tacky surfaces are obtained.  The effect observed is based on a synergism between the present photoinitiators. The advantages of the invention are most manifest in curing relatively thick layers of materials.

Abstract: ABSTRACT OF THE DISCLOSURE       An improved hydrate store for n metal halogen battery system is disclosed which employs a multiple stage, Multiple filter means for separating the halogen hydrate from the liquid used in forming the hydrate.          The filter means is constructed in the form of three separate sections which combine to substantially cover the interior surface of the store container.  Exit conduit means is provided in association with the filter means for transmitting liquid passing through the filter means to a hydrate former subsystem.  The hydrate former subsystem combines the halogen gas generated during the charging of the battery system with the liquid to form the hydrate in association with the store.  Relief valve means is interposed in the exit conduit means for controlling the operation of the separate sections of the filter means, such that the liquid flow through the exit conduit means from each of the separate sections is controlled in a predetermined sequence.  The three separate sections of the filter means operate in three discrete stages to provide a substantially uniform liquid flor to the hydrate former subsys em during the charging of the battery system.  The separation of the liquid from the hydrate causes an increase in the density of the hydrate by concentrating the hydrate along the filter means.

Abstract: METHOD OF EDITING DOT PATTERN DATA FOR        CHARACTER AND/OR IMAGE REPRESENTATIONS     Abstract For the layout of a page, text and image blocks with data for positioning them on the page are supplied to the data processing system.  The image blocks contain pattern information and the text blocks character codes.  The pattern information for the characters is stored in a typefont buffer.  For editing data to be recorded, "window storage" is provided, whose lines are cyclically associated with successive dot pattern lines on the page.  For this purpose, the window storage, figuratively speaking, successively assumes different window positions from top to bottom on the page.  The height of the window storage is chosen so that it is suitable for accommodating on the page a character with maximum ascender and descender heights.  This ensures that the pattern information of a character is transferred to the window storage at one go (in continuous periods).  The edit sequence in the window storage for pattern data of aligned or non-aligned lines of adjacent text blocks on the page depends on the sequence of the upper line boundaries and the baselines on the page, respectively.

Abstract: Abstract of the Disclosure Aqueous metal ammine siliconate solutions are the reaction product of selected metals or metal derivatives, selected mono-organosilicon materials, certain alkaline nitrogen compounds having the formula R-NH2, and water.          Amorphous materials are formed when volatiles are removed from the siliconate solutions.  The metal components in the resulting amorphous material are not readily leached out by normal weathering, washing or the like.  The solutions are useful in a method for treating substrates, such as wood, textiles, thread, canvas, carpeting, paper and masonry, to confer antimicrobial properties.  The organosilicon component can be selected so that the treatments also confer e?ther hydrophobic or hydrophilic properties to the substrates.  The components of the solutions can be selected to enhance their ability to form continuous films of amorphous materials when used in such treatments, making the solutions useful to provide antimicrobial coatings which may be either hydrophobic or hydrophilic.  Such amorphous coatings are useful for applications such as wood preservation, masonry water repellents, marine varnishes and as treating agents to give a desirable hand to fabrics.  Powdered amorphous materials can be used to produce antimicrobial ointments.  The solutions are useful as hardeners for water-reducible resins and emulsions, including latex paints.  The solutions can be adapted to include components which may be slowly leachable from the resulting amorphous materials which can thus serve as a controlled-release binder to provide prolonged antimicrobial protection not only to the treated surfaces but also to their immediate surroundings.
